Hello Paul,
The time template is irrelevant in this case, but what you're asking here is possible. You just need to make your tickbars value negative if you use a bar offset of 0. Your current code example is looking for the 20 tick bars into the future. Keep in mind this is only good when you are at bar 0. You will have a time synchronization issue on historical bars during the loading process.
one last question, will this "T" time template now make tick data accessible to efs e.g. if I use this in a 5 minute chart
var tickbars = 20;
var ticksymbol = getSymbol() + ",10T";
var tickhistory = getValue("Close", 0, tickbars, ticksymbol);
without the actual tick chart
var tickbars = 20;
var ticksymbol = getSymbol() + ",10T";
var tickhistory = getValue("Close", 0, tickbars, ticksymbol);
without the actual tick chart
